SNS 366: Machining New Stub Shafts, Sprocket Repair
Вставка
- Опубліковано 21 жов 2022
- We made it safely home after our trip up to IMTS. Soon as I returned I had some shafts to machine for the welding shop. These are stub shafts that will be welded into the ends of some roller tubes. I also had to bore and bush a sprocket. Some simple lathe work that we did in the Precision Matthews lathe.

Good to see a common shop job getting knocked out.
As he was such a valued employee at Motion, am surprised he never got any work from them after he left. Whilst employed there, he would a few times bring work home to do on his own machines.
SO refreshing to watch you doing straight-up lathe work! Flawless technique and that lathe is a beaut!
I had a similar job for my buddy . He bought a used asphalt roller that had a worn out drive sprocket.
He found a new sprocket that was exactly the same except the bore was 1" and the roller shaft was 1 1/4".
I bored it out to 1 1/4" and broached a new key way.
He was sure glad to get it.
You and blondihacks helped me make my first thing ever on a little craftsman 109. I’ve learned so much from your videos.
Nice to see her get a shoutout!
So you just HAD to make this about YOU? What are you a psychopath?
@@swedishpsychopath8795 what is wrong with you?
Love the approach, getting the work done is the only thing that matters.
They really got all the good out of those old shafts and the sprocket bushing. It's a miracle they didn't have a catastrophic failure.
I'm familiar with that type of roller equipment. RPM is maybe 10-15 max. "Catastrophic failure" would be a lot of rattling!! I am guessing those shafts reached "catastrophic failure". It is amazing the amount of wear that certain industrial equipment is sometimes asked to operate with.
Watching you set up and get you machining right on the money is one of the most satisfying and restful uploads for me. I used to ride/race Husqvarna motocrossers and lived out in the boonies of Wyoming. I had a good friend who taught machining at the locat 2-year college and he used to make pieces that I could not get in time for a race for me. Sometimes I would compare them to the actual part from Husqvarna and his pieces would fit better than the dealer. Hell of a machinist he was....he taught me a bit and I asked myself, "Why didn't I go into that?" Thanks for your uploads.
Kill,?
Great video as usual. One thing I always highly recommend to the guys when I train them on cnc is get a notebook and write down everything step by step so you have something to go back to. No one gets everything right the first time and until you use cnc daily your bound to forget stuff so having it written down so you have something to look back on is a huge help.
Exactly! Notes notes and more notes.
I stumbled upon your videos several years ago and have watched faithfully ever since. Never did any type of metalwork prior. I asked my wife if she could think of a reason why we would need a lathe. Of course she said no. Needless to say I found an older Rockwell/Delta (11x36) at auction from a local machine shop for $600. After refurbishing it (electrical, scraping, paint, etc) I sold it for $2900 and bought a LeBlonde lathe (18x58) and did the same. Sold that one for $6200. My goal is to buy a new one, all thanks to stumbling upon ABomb. To say I’ve had fun doing this is an understatement!! So thank you Adam.
I really enjoy your videos but your home shop videos just sum better to me now that your doing the new shop videos it just seems to be a machine shop video to me but I still watch them
You could start an ASMR channel for machined parts fitting into each other
I always enjoy watching Adam. Since I'm retired I don't have the need or even access to machining equipment but I still enjoy the process!
Love that PM lathe. Quiet and solid. Very nice to have that top-down view of grinding the radius. Those are the things that are really helpful for us beginners. SNS rocks! Thanks, Adam.
Fan at the back stage is HUGE. Like it!
It needs to be big to move air around his as*.
Nice to have you back in the shop doing some machining. Thanks very much for sharing.
I've been watching and appreciating all of your videos from day 1.
That's my Sunday morning treat,
Thank you.

What do you mean - are you a stalker?
@@swedishpsychopath8795 SW,I see you're still the AH you've always been with all your derogatory comments.
Very nice & precise work Ad.
Regards.
Steve.
Just like up town !!!
Thanks for the video.
Pressing that bushing was sooooooo satisfying!
The show coverage was great but can't beat hot chips!
Always like to have you explain and do -0-ing out on the 4 jaw chk.. Love to watch that indicator stop bouncing. Shop looks really nice...
This is so cool to watch!
As for the bushing “fit” I can hear my Dad say “it’s squeaking, must be a just right fit ! He had a way with words…… thanks Adam, nice way to end my Sat evening ❤️👍
That’s ok, the whole reason (well one of the main reasons) I watch your channel is because of the manual machining.
I'm mesmerized...what can I say😊
I keep coming back; not just for the content, but for the intro tune! 😎
Abom,your number one
Yeaaa. I'm hot to see that compound come together for the American Pacemaker.😊
I'm glad you are manual machining this, I'd rather watch stuff that a hobbyist like me would actually do. I sure as hell at 70 yrs old would never get into cnc, so this is good. 🙂👍
Definitely enjoyed watching this project. Filming was great as always. Thanks
Welding the disks and getting them centered in the rollers is going to be fun.
If the discs are cut accurately what's the issue?
@@Peter-V_00 Getting both shafts post welding to run true on one axis is needed to preserve bearing life. Maybe Joe has a rig for set up and for final run out checks before going out the door.
@@richardjones7249 Without knowing what welding process will be used you may be correct, then again for the application slight runout may be acceptable, from what Adam said the rollers turn slowly. If the person doing the welding is sharp they will know how to minimize runout, if I were concerned about being super accurate then the shafts should have been finish machined after welding.
Glad to see SNS back. Been missing that. Hi from Texas
Do you have a basement?
Hi Adam, I've been one of your biggest fans for a number of years! I first met you last year at Clark Easterling's Foundry. I just wanted to let you know, I love what you've been able to do with your new shop and all your new equipment! I've finally pulled the trigger and started a UA-cam channel of my own! Lots to learn, but having fun! Looking forward to our next meeting! Steve
Thank you for all the tips and tricks of your wisdom showing the years of experience!! LOVE your new shop!! I will say it- and bring it to fruition that you are already out of space and will need a bigger shop.
nice work Adam.. Enjoyed
What cool fit with bronze bushing to the sprocket….couldn’t feel it, but definitely could see and hear it😄👍 Nice work Adam😉
All your videos are great.
It is nice to just watch you work your trade though.
Thank you
That new lathe sounds so smooth.
Perfect timing! Just getting ready for my evening libation (I think a Single Malt tonight) and some snacks! What better to watch while enjoying them than Adam making chips! 🤣
Those used parts sure are long ago worn out. Seems that they need some harder metal but I have no idea how many hours they have on them now, likely tens of thousands.
Those custom jaws on the Wilton are what made that job work so well vs. old uneven and worn jaws. Nice.
Computer run equipment will rarely make a single small job worth programing which this video simply proved. Computer work is great but the time to program has to be taken into consideration when figuring out total investment time.
Thank you. Great job
Conventional machines are the best for repair jobs, good work!
Don’t worry about the CNC, I like watching manual machinist. When I started my apprenticeship you were not allowed to touch the CNC’s until you were skilled on the manuals. It’s not fun watching someone filming a CNC running, I want to see the manual guy doing wonders.
It's really cool watching you true the work in your lathe jaws with the dial indicator. Excellent radius work, too
You right. Its so much fun watching you use the four jaws. I used to regrind crank shaft as a young man and thank you for bringing back those good old-time memories. Blessed
agree nothing like fresh air
That’s the problem of learning a new way of doing the thing you’ve been doing your whole life. CNC has a steep learning curve if you already have knowledge of doing it manually. You basically researching your brain to do the same thing differently. Keep at it, Adam.
Nice job
Nice job Adam. I like the way the shaft fitted the bushing even after it was pressed into the sprocket.
Thanks for sharing.
I’m excited to see you try these jobs on the CNC lathe! We all love the analog machining, but you are now capable of sooooooo much more
New to your channel but like what I see. I know just enough to know how much there is to learn.
Always enjoy your 4 jaw indicating.
Gooood afternoon from central Florida! Hope everyone has a great day!
I'm a retired machinist, got a little job shop. i really like the whole process of manual machining, i have never been able to gather any enthusiasm for sitting at a computer and watching something spit out parts. if it came to that i would just buy the parts or pay to have them produced
Great video Adam, keep'um coming.
I would like to see a video of you making your own hydraulic press. I think that would be some awesome content.
That would be awesome! Welding, fabrication, lathe work, mechanic work, it's all there. Making a cylinder from scratch would be fantastic.
I'm suprised they didnt weld the new stubs into the tubes before asking Adam to finish the journal sizes. That welder has job a fun job ahead of him maintaining those centres.
Wow, the new shop has filled up! Glad you pointed out that sometimes the manual way is best over cnc everything. Especially for just a couple parts at a time. CNC has it's place , mostly for something that will be repeat business.
I have that same Wilton vise on the back of my welding truck.
That is why Trak conversational programing is so much better Miltronics.
So simple to program plus the option to make it difficult with G and M code
Great video. Excellent machining. Thank you for sharing.
Perfect job,Adam.Thank you.
Job well done. Always enjoy your work.👍😁
Mr. Booth you are an expert machinist.
Nice work. Amazing as always ❤️
"that tool acting like high" is a sentence, exist and I hear all the time
Huh?
I always love these videos and, as others have said, they are very helpful for us beginners.
Cool videos on the IMTS show.
The ability to do radius cuts on the cnc would have been worth it to me, but if you had to hurry and get that out can't blame ya for sticking to what ya know. I just got a proto trak cnc mill that is conversational and it's pretty cool being able to just program the actual geometry not the toolpath. In a month I've gotten to where I wrote a program to make a weld on pin flag put of 3/8 plate in about 10 minutes. Being able to cut circles and complicated profiles on the mill will make life much easier even in a job shop. I suspect you'll feel the same way once you get the hang of it. Cnc will never replace some manual work but it can make some manual work much less complicated.
Man that grinder is soooooo Smoooth! I enjoyed that video where you upgraded/fixed it. This one too... hell all of them! :D
It is nice, I guess, but he is using it wrong. The stone is already worn uneven on the left side (seen from his view). He should've moved it slowly from side to side to make it wear evenly.
@@swedishpsychopath8795 I'm 100% sure he is not. It's a grinder... You can put your own profile on it for the way you work
Welcome back Adam and Abby. awesome video
I love that lathe. Thanks Adam.
Did he give the lathe to you? Why are you thanking him?
@swedish
Have you thought about seeking help?
@@jessiepooch That was rude.
Adam your the only only one that does chip control….that I see on other UA-cam videos. These shafts turned down beautifully AND have the benefit of the chips going straight down into the pan. I’m not a professional machinist, but why would anyone want hot chips hitting there arms/body, shooting all over the machine and floor? Just makes sense to have the best possible insert for the job👍 Thanks for sharing that it’s possible to control where the chips go🙂
Thanks for getting back to cutting iron...good job!
Hi Adam, I like your new shop, it looks fantastic and well laid out. You must look forward to getting up each day and going to work. Oh yes I would have the door up as well. Cheers Ian New Zealand
Very nice work!
Awesome job.
Solid work.
That Brass jawed Wilton, is officially "im-press-ive" ;)
Royal quad bearing centers are awesome we ise them all the time making electric motor shafts
To be fair, with only four off (and not even identical) and such a simple part, it's probably a manual job even for shops which have a well practiced CNC turner
Hey Abom, using carbide insert profiled for aluminum work really well for lighter cuts on 1018 if you want great surface finish. Obviously they wear out much faster than steel profile inserts but they still last quite a while(especially TCMT with the three cutting edges per insert).
Thanks again for sharing
Seeing the camera fixed on the lathe and talking about heat, I think it would be really interesting to see an infrared image while working on a job. Maybe look at how heat distribution affects measurements? Anyway, always enjoy whatever you do!
I'm a sick pup. I work in a design shop and watch most of you, Keith Rucker and Blondihacks videos on the weekend.
Blondi is GARBOOOO, pure garbage. She needs to make a compass and lead herself back to the kitchen mmmhm
what a way to a saturday. night. thanks learn lot
Thanks for sharing
I have a hard time using my cnc on projects that I am so comfortable with doing manually. I find using the cnc that it easier to forget how to do something than to learn something. So it is a tough learning curve. However if you are doing a lot of parts you can’t beat cnc once it is set up.
Cool video
Good stuff
Before I retired I used to rebuild M/C cylinders. I'd bore out the to cylinder to -.0015" clearance and then heat the cylinder and freeze the sleeve. They'd drop in and then be tight as a drum when cooled.
Cool crisp 87° Florida air, haha
Talk about your watch(es) on an episode at some point please. Watch geek here, along with enjoying all of your other videos for the last 3 years!!
Adam, yes although you are confident with manual lathe it would have more value if you force yourself to use and learn the cnc. Using those shafts as practice later is a good idea too. Once you do it you'll realize you could have done it just as well on the cnc as on the PM. I worked at 3 cnc machine tool companies and it was difficult helping the machinists convert to cnc. Keep trying, you'll get there. Yes, take detailed notes. Great video my friend.
I was disappointed in Royal, I bought a used Royal like yours in a MT3 and while the bearings are in great shape it needs to be reground and I don't have the means to do it so I contacted them twice to see if they would regrind it for me and never could get a response from them.
I ended up buying a new Skoda and I've been very happy with it but I would still like to get the Royal reground as a back up. I've looked around and seen a few third party places that recondition them but haven't gotten around to having it done.
Enjoyable video.
For the CNC lathe and simple stuff I'd recommend a program template for you. Copy and paste then renamed. Has all your cycles in with preset safe starting numbers. All you change is profile code. Still involves all the math you use on the manual lathe. More hands on where you would feel familiar. Much less point and click memory.
He is just like a demented old grandpa. He doesn't remember sh** from what he learned 5 mins ago.
When you get bewildered on something with new methods, you default to what you have the most experience with. You go from CNC back to manual, I still find myself going back to torch & grinder when I find I'm not equipped or knowledgeable enough for a certain task on the machines ... makes me disgusted with myself, as I got the machines so I could get away from most of that. Always more tooling to get, or more to learn. I don't mind the learning except when it's one of those jobs where you can't afford a serious mistake or you have to get it done as quick as possible.
Adam has a good pragmatic attitude about all this stuff like CNC vs. manual. He’s not afraid to learn but a person has to evaluate where he or she is with anything of this nature and make good decisions.
Repetition is the key - Like most skills, if you don’t use it you loose it… to some degree, CNC is no different, unless you are completely happy with your programming you’re just wasting time and materials, On a positive note Adam - manual skill and ready reckoning in a machine shop is invaluable- maybe it’s time to take on an apprentice to pass on your skills and help you learn some new one’s..😁💪🏻💪🏻💪🏻
Nice
